The story of Sedna, which is a creation myth, describes how she came to rule over Adlivun , the Inuit version of the underworld .
Sedna has no symbol in astronomical literature, as the usage of planetary symbols is discouraged in astronomy. Unicode includes a symbol (U+2BF2), [28] but this is mostly used among astrologers. [29] The symbol is a monogram of Inuktitut: ᓴᓐᓇ Sanna, the modern pronunciation of Sedna's name. [29]
One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...
The former name was later used for 90377 Sedna, a distant trans-Neptunian object discovered in 2003. [23] I sent [Kavelaars] that bit about Siarnaq, or we call her Nuliajuk, that creature that lives under the sea, who's also know as Sedna. She's got so many names ... sometimes she's simply called the Old Woman Who Lives Down There.
90377 Sedna, a large trans-Neptunian object, had the provisional designation 2003 VB 12, meaning it was identified in the first half of November 2003 (as indicated by the letter "V"), and that it was the 302nd object identified during that time, as 12 cycles of 25 letters give 300, and the letter "B" is the second position in the current cycle.

Sedna is a trans-Neptunian object with the asteroid number 90377. It was discovered on November 14, 2003 by astronomers Michael Brown , Chad Trujillo , and David Rabinowitz . Sedna is currently 88 Astronomical units (AU) from the Sun , which is three times the distance between Neptune and the Sun. Sedna's orbit is an ellipse and its aphelion is ...
The NASA image is not the same as the uploaded image (note the bright object to the left of Sedna is below Sedna in the NASA image(s), but well above it in the uploaded image). The uploaded image is from Caltech and, as the source is a direct link to the image itself (a problem in itself), there's no authorship attribution.
